Are Glass Staircases Safe?

Manufacturing the glass railing spiral staircase using safety glass panels ensures safety and compliance with current building regulations.

Safety glass, a robust and secure type of tempered laminated glass, surpasses ordinary glass in strength. Its widespread application includes car windows, windshields, and residential projects like interior glass bridges, doors, and shower doors. Commercially, it finds use in storefronts, tables, and canopies.

Tempered or toughened glass

The tempering enhances glass strength, reducing the likelihood of breakage. If breakage occurs, tempered glass shatters into small, safe, round pieces, avoiding sharp edges.

Laminated Glass

A lamination process enhances safety by keeping the glass pieces together in distinctive panels. Witness the consequences when glass steps break:

Laminated Glass

The glass panel stands as a distinctive component, free from dangerous debris or sharp edges, ensuring safety.

But that’s not the end of it. Some customers want broken glass as a unique feature or pattern on steps or railings. This is the railing we recently designed.

Glass treads

Our glass railing spiral staircase steps typically consist of tempered laminated glass, approximately 33 mm thick. This comprises three layers of tempered glass (each 10 mm thick) sandwiched between two layers of 1.52 mm PVB film.

Glass balustrades

The glass on the railings and railings has a thickness of 21.52mm, with two layers of 10mm tempered glass bonded by a layer of 1.52mm PVB film.

These thicknesses ensure a remarkably high level of safety, aligning with staircase building regulations in numerous countries globally.

Are glass stairs safe? Glass fastening system on stairs

The safety of a staircase relies on both certified safety glass and the fasteners securing the glass to the main structure, like the central spine or stringer. We exclusively employ systems that undergo testing and structural inspection to meet the necessary load-bearing requirements.

Glass fixing systems on landing balustrades and guard rails

At the top of stairs, railings are often necessary to safeguard ceiling openings or mezzanines. In such cases, both the ceiling and mezzanine must be structurally sound to bear the loads of the glass balustrade, ensuring the safety of the installation.

Various methods exist to secure glass balustrades to a slab or mezzanine. Are glass stairs safe? Glass fastening system on stairs. Alternatively, an elegant and seamless system involves concealing the glass fixings with stainless steel, powder-coated, or wooden panels.

If you want to secure your glass railing to the top of the ground, we can use aluminum railings to secure the glass. The tracks are often hidden underground, so the glass protrudes directly from the ground with no visible supports.

Are glass stairs safe? Anti-slip properties increase safety on glass steps

The glass pedal features two to three frosted strips, providing a not-too-slippery surface. While this option exudes elegance, keeping frosted strips clean can be challenging at times.

You also have the option to adhere anti-slip strips to the pedals and replace them periodically.

Yet, the most elegant choice is an etched glass pedal, even though it comes at a higher cost.

Top Safety Considerations of Glass Stairs and Glass Treads

Stepping cautiously onto clear stair treads might quicken your pulse, but is there a real cause for concern? Despite the sensation of walking into nothingness, glass stairs are entirely safe—as long as they possess these four crucial features that demand attention.

What are the safety benefits of a glass staircase?

In many cases, a glass staircase stands out as one of the safest options for your home. Here are just a few of the benefits:

They're extremely durable and long-lasting?

Glass remains highly robust, enduring without degradation over time.

While other materials may rot or rust, glass stands firm throughout its life, serving your home for years.

It’s also exceptionally resistant to impacts, avoiding major structural damage.

They're child and pet friendly

Whether you’re a parent or a pet owner, slips and stumbles are familiar occurrences.

Wooden or metal railings pose a significant risk to eager little limbs, but glass balustrades are designed with gaps too small for them to fall through. This not only enhances safety but also ensures that no visual elements are compromised.

3. Glass-Specific Engineer

Equipment for crafting glass stair treads is easily accessible. Numerous glass manufacturers provide this service, but rarer are companies with the experience, expertise, and professional processes to execute these projects with the utmost safety, durability, and aesthetic appeal.

The emphasis lies in collaborating with glass manufacturers who involve glass-specific engineers in every project. These professionals undertake calculations and designs to guarantee the safety of any architectural glass project.

They form an essential part of the glass manufacturing team. Optimal safety requires a product that aligns seamlessly with your glass staircase project.

4. Appropriate Glass Thickness

Glass railing spiral staircase tread thickness varies depending on your project’s needs, aesthetics, and design.

That’s why a reliable glass professional is essential. They utilize international building codes, glass safety standards, and project-specific details to craft the safest stair treads.

Glass engineers consider various details when determining the required thickness of stair treads:

Staircase location (internal or external)

Expected load

The private or commercial sector

Size, shape, and span of each tread

Supported system details

Appropriate Glass Thickness

All Safe Glass Staircases Have These 4 Features

Before partnering with a glass manufacturer for a staircase project, ensure they integrate these essential safety features into their products and processes.

1. Anti-Slip Glass

One of the most common questions and concerns about architectural glass is whether it’s smooth or not.

When anti-slip glass is executed correctly, concerns about slips, trips, or falls become obsolete. Technologies differ, but the concept behind anti-slip glass is to enhance friction during walking.

This is achieved by:

Fusing glass aggregate to the tread

Baking on a non-slip surface

Etching the tread with acid

Stair treads are treated properly to ensure safety in both dry and wet conditions.

Anti-Slip Glass

2. Failure Redundancy in Glass Treads

Each stair tread should consist of three separate glass pieces “sandwiched” together, a critical component for the safety of your glass staircase.

In case one glass piece fails, the system still has two intact pieces to support the weight. It’s designed, engineered, and manufactured to maintain structural integrity even if such a failure occurs.

Implementing this manufacturing technique not only enhances the safety of your glass staircase but also ensures compliance with today’s American Society for Testing and Materials (ASTM) specifications.

Avoid any glass manufacturer not utilizing this failsafe method in their work or providing insufficient, unprofessional answers when questioned.

Remember, if the architectural glass in your home or business is structurally unsound, everyone involved, including yourself, bears responsibility for the consequences.

Failure Redundancy in Glass Treads

They're transparent

This isn’t just stating the obvious.

The transparency of the glass, besides being a crucial visual feature, serves as a potentially vital safety element. It allows for better visibility and judgment of height.


In conclusion, the safety of glass railing spiral staircase hinges on meticulous design, quality materials, and proper installation. While some may express concerns, a well-constructed glass staircase, that meets safety standards, can indeed be a secure and stylish addition to your home or commercial space. By considering factors such as glass thickness, railing design, and adherence to building codes, you can mitigate potential risks associated with glass staircases.

Ultimately, glass staircases can provide a contemporary and open feel, but it’s crucial to prioritize safety in their conception and installation. So, when pondering the safety of glass staircases, meticulous planning and adherence to safety standards are key to achieving a stunning and secure architectural feature for your living or working space.
